Terms and Definitions

Angina is a medical condition characterized by severe chest pain or discomfort resulting from decreased blood flow to the heart. This condition generally occurs when part of the heart isn't receiving enough oxygen and is mostly caused by narrowed or blocked coronary arteries.

Prevalence refers to the total number of cases of a specific disease present in a certain population at a given time. It is a statistical measure used by researchers to estimate the commonality of a disease in a certain area or population.

Coronary arteries are the two major blood vessels that supply the heart muscle with oxygen-rich blood. They wrap around the outside of the heart, and when they narrow or become blocked, it can lead to heart diseases such as angina or a heart attack.

Chronic disease is a long-standing condition that can be controlled but usually not cured. Chronic diseases are characterized by their long duration and slow progression, common examples include heart disease, diabetes, and cancer. Angina, in this context, is considered a chronic disease due to its ongoing management challenge.

Risk factors are attributes, characteristics or exposures that increase the likelihood of developing a disease or health problem. In the case of Angina, risk factors may include older age, smoking, high blood pressure, high cholesterol levels, diabetes, and a family history of heart disease.
